Problems solved by technology

However, this design of the notch will lead to differences in the grid line signals of the pixels on both sides of the notch and those of pixels in other display areas, and this difference may cause the problem of display unevenness (Mura)

Abstract

A display substrate comprises a display area, a grooved area and a capacitance compensation area. The display area at least partially surrounds the grooved area, and the capacitance compensation area is located between the display area and the grooved area. The capacitance compensation area is provided with a first capacitance compensation unit. The first capacitance compensation unit comprises a semiconductor structure, a first metal structure and a second metal structure which are sequentially arranged on the substrate. The insulating layer between the semiconductor structure and the second metal structure is provided with a plurality of first via holes, and the second metal structure is connected with the semiconductor structure through the plurality of first via holes. The first metal structure includes a plurality of second gate lines extending along the first direction. And the second grid line, the second metal structure and the semiconductor structure form a capacitor. The plurality of first via holes are arranged along a first direction, and in a second direction perpendicular to the first direction, the distance between two adjacent first via holes is at least greater than the sum of the widths of two second grid lines.

Description

technical field [0001] This article relates to but is not limited to the field of display technology, especially a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] With the rapid development of display technology, consumers have higher and higher requirements for the appearance of display devices. Many display panels have changed from traditional square shapes to current popular special-shaped structures, such as rounded corners in the display area and special-shaped grooves in the display area. etc. The special-shaped structure is undoubtedly a challenge to the manufacturer. For example, shaped displays with notched designs (eg, "notch" screens) are increasingly being adopted by mobile phone manufacturers. This special-shaped display is conducive to obtaining a higher screen-to-body ratio, and the notch design in the display can reserve design space for components such as the front camera. However, this design of the n...
